براغي ذات رأس سداسي M20-1.5 × 100 مم | فولاد فئة 8.8 عادي | ملولبة جزئياً (25 / عبوة)

Heads are clean and uniform, so the hex wrench doesn't slip even under heavy torque. These M20 bolts held a steel jig frame together perfectly.

Installed these on a heavy steel frame I'm building, and the partial threads let me cinch down the joint perfectly. The class 8.8 steel feels solidly made and consistent across all 25 pieces.

Wrenches fit the hex heads perfectly, and the 100mm length was just right for securing a heavy bracket without needing extra washers. The partially threaded shank made alignment quick, and the class 8.8 steel feels solid enough for industrial use.
